I believe the correct answer is: A person can experience the calm of the pleasure dome and the chaos of the wilderness outside.
In the “Kubla Khan”, written by English poet Samuel Taylor Coleridge in 1797, the “miracle of rare device” symbolizes that person can experience the calm of the pleasure dome and the chaos of the wilderness outside. Coleridge uses contrast between the dome and the wilderness – natural versus man-made, below and above the ground, frozen and warm, to create a harmony and show the experience of the pleasure.
